Interpretive Summary:

Technical Abstract: Fall-planted Brassica species can suppress weeds, nematodes, insects, and diseases in crop rotations. Pest suppression is often attributed to decomposition products of the Brassica cover crop. Some of the main decomposition products of Brassicas are istohthiocyanates which are derived from hydrolysis of glucosinolates present in the plant tissue. The quantity and chemistry of hydrolysis products of glucosinolates depends upon plant part, plant age and environmental conditions. Allyl isothiocyanate is a potent inhibitor of weed seed germination and weed seedling growth.
